Substrate-Driven Modulation of Photon Pair Generation in Quantum Optical Metasurfaces
Most modern quantum light sources are based on spontaneous parametric down-conversion (SPDC) in bulk non-linear crystals, with strict phase-matching requirements that limit their design flexibility and the range of two-photon states produced. Recent research has focused on generating quantum light via SPDC with metasurfaces [1], i.e. array of nanoresonators with sub-wavelength dimensions. At this scale, SPDC becomes independent of phase matching, allowing the use of materials with greater nonlinear susceptibility and enabling efficient photon generation with tailored properties for the angular and spectral distribution and polarization.
